Tropical Storm Nana formed Tuesday afternoon in the Caribbean south of Jamaica. This system poses no risk to the United States, but could bring some impacts to Central America and the Yucatán in the coming days.
Nana is expected to continue on a westward track and enter into the western Caribbean Sea late Tuesday. Heavy rainfall and gusty winds are expected to continue across Jamaica as the system moves just to the south of the island. Conditions will begin to deteriorating in parts of northern Nicaragua, Honduras, Belize, Guatemale, and the Yucatán by Wednesday. A Tropical Storm Watch has been issued for the northern coast of Honduras from Punta Patuca westward to the Guatemala-Honduras border, including Roatan Island and the Bay Islands of Honduras.
The National Hurricane Center says that additional development is expected Tuesday and on Wednesday, with Nana possibly reaching hurricane strength Thursday as it approaches the shores of Central America. Nana is the earliest "N" storm of record, the previous record was Hurricane Nate which formed on September 5th, 2005.
